Treatment of Ureteral Fibroepithelial Polyp by Ureteroscopy Combined with Holmium Laser or Thulium Laser: A Retrospective Study.

Background and objective: Ureteral fibroepithelial polyps (UFPs) are rare benign tumors and ureteroscopy has been used for treatment. We compared the effect of UFP by ureteroscopy combined with holmium laser or thulium laser. Methods: Twenty-five patients with UFPs were treated in our hospital between May 2003 and April 2013. All patients received ultrasound check and intravenous urography (IVU). We performed ureteroscopy operation and found ureteral polyps, so we resected the polypswith holmiumlaser (12 cases) or thuliumlaser (13 cases). During the 3-year follow-up, all patients received IVU2 or 3months after the double-J stent was removed, and ultrasonic checks every 3-6 months after that. Results: All patients had UFPs resected. Three patients in the holmium laser group had ureteral perforation during operation, and four patients in the holmium laser group developed ureterostenosis. No patients in thulium laser group experienced any severe complications during the procedure. Further, during followup, there was no indication of an increase of hydronephrosis in any patients. These findings lead to conclude there were no developments of ureterostenosis nor an experience of any reoccurrence in thuliumlaser group. Conclusions: Ureteroscopy operations, combinedwith holmiumor thuliumlaser resection, are effectivemethods for treatingUFP, but thulium laser does better in reducing the incidence of ureterostenosis.
